Archmage Jaina Proudmoore is the most powerful human sorceress alive.She is the daughter of Grand Admiral Daelin Proudmoore, he was the supreme commander of the naval forces of the Alliance. He also had a second daughter outside of his marriage with an elven sorceress names Kilnar Goldensword.
People aware of lores from Alagasia might construe that their love was real for elves consider children as the greatest symbol of love.
As with Harry, when her magical talents were discovered, she was sent to Dalaran to study magic under the watchful eyes of a master. There she became archmage Antonidas's protegee.
Dalaran was a magacracy - a form of government in which society is ruled by mages.Its Violet Citadel at Cross Island served as the focal point for mages and the study of the arcane rituals throughout human history.
She was a bright kid and soon Antonidas found himself favouring his new apprentice.Jaina would have served in the high council of Dalaran had it not fallen in the third war.
Jaina had a rather sad fortune as far as relationships go.
First she was involved with Prince Arthas was has now become the greatest evil know to man and is undead now. Then there was the elven-mage Kael'thas who became a magic addict. And there are speculations regarding her relationship with Thrall who is an Orcish warchief. None of the above characters are human so as to say, atleast not now.
She accomplished much in her service to Lordaeron. She was sent to investgate the Plague at the northern village of Brill. There she got entangled with events greater than she had known before. It was a tip of Lich king's plan( Orc chief named Guldan) to unleash the burning legion upon Azeroth. The plague was caused by contaminated food distributed from Andorhal to the rest of Lordaeron. It transformed villagers into zombies who would serve the undead. The plan was executed by a necromancer named Kel'Thuzad.
The undead plan worked so well that soon it engulfed entire Lordaeron. Jaina led her people to the land of Kalimdor. There she befriended orcs and night elves and faught the burning legion under a united front. Together they defeated lord Archimonde.
Later Jaina took her refugees to an uninhabited island off the eastern coast of Kalimdor, and named the new outpost Theramore.
